Be it known that `DGARL Pnirnnsson, a citizen of Sweden, and a resident of jBi oklynf, in the county of Kings and State of New York, have invented certain new and useful y Imlowing is a specification. f Myinvention relates to refrigerators, pref- "erably of large size, and such inwhichit is desired to obtain avery low temperature, even -glow enough for freezing. i. n The invention comprises arefrigerator made in sections in such `a manner that it can be taken apartfor carrying and shipment, and theninay be brought inthrough ordinary doors and put up in any place desired, to whieh its size otherwise wouldprevent access with it; `It alsoV comprises' `the lConstruction, combi;- nation, and arrangement "of the various parts, as will be hereinafter described andclaimed. n In the accompanying drawings, Figure l rep resents a vertical section of myimproved refrigerator, the section1 being supposed 1to` be taken on about the line x m of Fig. 2; Fig. 2 y represents a horizontal section of thesame, taken on the lineifzjg/ of Fig. 1w` Fig. 8 is a vertical section of the` casing on a smaller i scale than any of the previous gures. Fig. 4 is a top view of the ice-chamber cover and of the preserving or freezing chamber with its cover removed. Fig. 5` is an enlarged "sec tion taken onthe linezz ofFig. l. l The casing is made in two or morev separate parts, A A, the lower one, A, being in the shape of an ordinary squareboX withbottom and feet to support it, andeaeh of thesubseT w quent sections Abeing four sided, without bottom, and of'proper size to `iit eXactlyupon i the lower section, A, `and having hooks piv-` oted upon the inside of each of its four `walls, y `which hooks engage with pins or staples upon the inside of the four walls of the lower box ,orsection The inner non-conducting lining of the refrigerator is made in four pieces, B B l B AIB, each consisting of a hollow wooden wall filled with `charcoal and covered withfelt b. `These liningsections B have `beveled edges, `forming an angle of forty-,five degrees, and are "of proper size to lit tightly Within the casing, A A', and, when within the casing, to join" each other at theiredges, the felt b (which `covers also the beveled edges) `forming an air-` UNITED- STMES4 cant rnrrnnsson, on BROOKLYN, nnw YORK.

ered withzinc c, and `having perforations to allow ofithe water `from the melted ice run- `ning throughit toa chamber, D, the said chamber `being formed between the bottom of the box or casing A and the aforesaid false bottom C by supportingV the latter upon suitable cleats or ribs, c, fastened within the casy ing A, as shown in Fig. l. The bottom and sides of the water-chamber D are covered with zinc d; i d

In one part of the chamber D is inserted a small glasstube,` E, communicating at itsupper andlower ends with the top and bottomof the chamber D, so as to allow the 'water in the said chamber to freely enter the said tube E.

' The. height` of the water may be observed from the outside Ofthebox by raising the small sliding cover F, tted between cleats j', and which, "when slid down to its place, `protects the glass from injury, as shown in Figs. l and 5. From the side of the box, at the bottom of the chamber D, is inserted astop-cock, G,

y by which the water in the chamber D may be drawn oifat times, so as to prevent it from gradually rising above the false bottom C.

The preserving and refrigerating chamber is formed `of a square metallicboX, H,.prefera bly of zinc. l`This issupportedupon the falseV bottom G by four intervening feet orother support,`l1,` and is provided with a. central projec-` tion, .f/,which is inclosed in a socket, d', (said socket being formed upon the false bottom 0,) and by which, also, the chamber H'andits con-` tents are supported upon the bottomC. In

`order to relieve the said false bottom of excessive strain by theweight, the said projection g is provided with another projection, f/,which goes through a hole in the false bottom and rests with `its lower` end upon thebottom of the casing A, thus `dividing the weight between the false andthe permanent bottoms, as shown in Fig. l. The object of the rim d', which forms the aforesaid socket to receive the IOO 2b intheir edges in position to pass the supportcentral support, g, is to prevent the crushed mon cover,v0, which may be made hollow and'I ice from getting between and interfering with the direct supporting of the projection g.

The box H is divided by shelves I J K into compartments, the said shelves being of suitable size and shape to fill the cross-section of the interior of the box H, and resting upon stops or small cleats h h2 71., secured upon the inside of the box. In order to provide for a difference of temperature in the different conipartments, so that a freezing temperature may be obtained in the lowest compartment and a somewhat higher preserving` temperature may be obtained in the upper compartment. the lower/portion of the box is in direct contact with the surrounding ice, while the upper portion .is covered on the outside with felt L.. In order to allow of lowering the shelves to rest upon their proper supportingstops, the two lower shelves I J are provided with notches ing-stops of the super-jacent shelves, while the stops which support each respective shelf are arranged at places not in linewith the said notches, as indicated in Fig. 2. To the center of each shelf is secured a rod, by which its contents'may be lifted out of the box H. For this v` purpose the lower shelf I has a small central rod, t', reaching up to near the top of the box H, on a level with the cleats h2. The said rod z' is provided witha shoulder, t', upon which the next superjacent shelf, J, is`also supported. This latter shelf has another hollow rod or sleeve, j, fitting easily upon the rod 1i, and provided, on alevel with the upper stops, h, with a shoulder, j', which in a similar manner supports the shelf K, the latter beingalso provided with a tubular rod, 7c, fitting easily upon the tube j. IBy this construction it is evident that the shelves K J I may be lifted out of the box successively, one at a time, by grasping the rods kj i successively, or all three, with their contents, may be removed simultaneously by a hook or some similar means inserted through a small hole in the upper end of the rod t', said hook being attached to a suitable cord and hoistingtackle arranged centrally above the refrigerator.

The refrigerator-box H is covered ontop with a suitable lid, M, provided on the under side with a backing of cloth,f,l m. The ice-chamber which surrounds the box H between the latter and the lining B is covered on top with aframe or angular cover, N as shown in Figs. l and 4, the said cover being also covered underneath with felt oz, and supported upon suitable cleats, o, secured to the inside of the lining B. The entire refrigerator is covered by one comiilled with non-conducting material, if desired, and is` preferably hinged at one of its edges in the usual manner of ice-boxes.

It will be seen that the refrigerator-box H is surrounded by ice on all sides, and that there is no side door to the apparatus, but that the shelves with contents, as well as the inner box, H, itself, are removedand inserted,when occasion requires,by being lifted or hoisted out,

after first removing the cover O as well as the covers m n, when required.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a refrigerator, an inner lining made of separate hollow walls B, filled with non-conducting material, and having beveled edges provided with suitable non-conducting packing, b, in combination with an inclosing-casing, A, substantially as hereinbefore set forth.

2. In a refrigerator, the combination of a casing made of detachable sections, AA, and an inner non-conducting lining, also made in detachable seetions,B, substantially as and for the purpose set forth.

3. In a refrigerator, the combination of the sectional casing A A, the perforatedfalse bottom C, supported to form a water-chamber, D, above the bottom of the casing A, the nonconducting and felt-covered lining B, and the inner refrigerating and preserving box, H, partly covered with felt L, and supported,sub stantially as described, so as to form a surrounding ice-chamber between itself and the lining B, substantially as and for the purpose setforth.

4L. In combination with a box, H, the same forming the inner freezing or cooling chamber of a refrigerator, the shelves I J K, provided with their respective rods t j k, for Vremoving and inserting said shelves successively and simultaneously, substantially as hereinbefore set forth.

5. In a refrigerator composed of the inner freezing chamber, H, the ice chamber surrounding the same, the incased non-conducting lining-walls B B B B, perforated bottom C, and water-chamber D, the combination, with the said water-chamber, of the glass gage e and discharge-cockG, as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as my invention I have signed my naine, in presence of two witnesses, this 2d day of March, `1883.
